YouTube Data API: Exclude livestreams from Search.list result set

Today I have an (I think) simple question.I want to exclude YouTube live streams from my YouTube Data API Search.list result sets.How can I do that? I can't find a function to do that in the docs from the API.

That's what I tried:

https://www.googleapis.com/youtube/v3/search?channelId=UCZMsvbAhhRblVGXmEXW8TSA&part=snippet,id&order=viewCount&maxResults=1&regionCode=DE&eventType=completed&type=video&publishedAfter=2021-02-05T00:00:00Z&key={KEY}

But that includes live streams, I want to remove them from the search. The live streams has always LIVE in the video title, maybe that helps. I tried also to use q, but I get always 0 search results.
